Replying in a semi serious way, the March 10 QST article by N6LF and its

He is wunderin....did I improve or degrade my signal???....and he wonders if he could measure current flow in the 1/4" ground bus to the ground rod...would it show any current flow and how would that compare to the current flow in the radials....???? Will his SWR change?
